I am sending you a few bugs that are destroying the rose foliage and other shrubbery in the cemetery. Would like to know of some remedy as soon as pos- sible. E. A. B.—Mich. The box contained a number of rose chafers, commonly called rose bugs. A special article on these appeared on page 89 of The Review for June 15, which please peruse carefully. These destructive insects have a marked par- tiality for white flowers and are espe- cially harmful to white roses, white peonies, hydrangeas, tree lilac, Syringa japonica and grape vine foliage, but also attacks some other plants. While they can be killed by poison sprays, the use of arsenate of lead makes foliage white for a long period, and the rose bugs will leave the poisoned part and attack any of the new, unsprayed por- tion or opening flowers, rendering addi- tional spraying necessary. I should sug- gest that you get a can of Melrosine, a comparatively new preparation on the market, which I find kills all rose bugs which it hits and disfigures foliage hardly at all. If you cannot readily procure this, I would spray with ar- senate of lead, although it will some- what disfigure foliage more or less. C. W. TEMPERATURES FOR ROSES. Can roses be made to bloom in a night perature of 50 degrees at night and 65 grees during the day? Will the garden varieties be more apt to do so than the varieties generally used for forcing? M. P. F. C—Wash. Roses can be made to bloom in a tem- perature of 50 degrees at nights and 65 degrees during the day, but the plants will not throw nearly so many flowers, though what flowers arc produced will be of a much finer quality than those produced in a higher temperature. The reason that the average rose grower holds his house at 58 degrees to 60 de- grees at night and 75 degrees during the day is to keep the plants alive and active ami producing at all times to their ut- mos
